Theory of sonics

Thus, the inventor has funded a company and has managed to win an auction which allowed constantindscu to build 5 bridges across the country. If valve b is open, the motor m is able to take the energy from the line, the stationary half-wave between a and b being replaced by a traveling wave; between b and p a stationary wave will persist.

We all know at least a few famous inventors, however, some like Gogu Constantinescu have never become famous for unknown reasons. From to his first invention until the year of his death, in his most prolific time, Constantinescu will average an invention patent per month.

If Nicolae Tesla invented and transmitted electromagnetic waves electromagnetic oscillations through the atmosphere, George Constantinescu invented mechanical sonic oscillations with which he transmitted sonic waves only through continuous media tubes or pipes, water, oil, various liquids, air, gas, or full bars.

He was responsible for creating a new field of mechanics, called “sonicity,” which describes the transmission of energy through vibrations in fluid or solid bodies. Please help to improve this article by introducing more precise citations. Retrieved 25 July Later on, in his life, he has projected several well-known buildings throughout the country including the Sports Stadium ,the Chamber Commerce building, and the Constanta mosque.


Archived from the original on 27 July So every four months he get a patent for an invention, patents that reachingabout they were unique and amazing for that time undiscovered yet until then. The above equations are used in order to calculate the springs required for a condenser of a given capacity required to work at a given maximum stress.

His hydraulic machine gun synchronization gear allowed airplane-mounted guns to shoot between the spinning blades of the propeller.

The system was not adopted on British railways but it was applied to some railcars on the Romanian State Railways. His inventions patents were obtained in countries like: By using this site, you agree to the Terms of Use and Privacy Policy. He had several patents for improvements to carburetorsfor example US Retrieved 24 July A Treatise on Transmission of Power by Vibrations. The Constantinesco synchronization gear or “CC” gear was first used operationally on the D.

A small calculation shows that since the first inventionuntil the date of transition to eternityon average every 4 months a patent was made and if we constantinecu only the most prolific years, it results in invention per month. Constantinescu has continued his successful career, building bridges over Siret in Adjud, Constantinewcu and Racatau.

If p 1 is the pressure at an arbitrary point and p 2 pressure in another arbitrary point:.

It was also tried on rail vehicles. For pipes with greater diameter greater velocity can be achieve for same value of k. In a pipe were the currents are flowing, we will have:. Views Read Edit View history.

According to constantnescu new system, energy is transmitted from one point to another, which may be at a considerable distance, by means of impressed variations of pressure or tension producing longitudinal vibrations in solid, liquid or gaseous columns. The pipe is closed at p, a distance of one complete wavelength. Use dmy dates from July Articles lacking in-text citations from March All articles lacking in-text consttantinescu.


Archived from the original on 20 March If the crank continues rotation at uniform speed, a zone of maximum pressure will start from the piston at the same time the reflected wave came to the piston, as a result the maximum pressure will double.

If the motor l is not capable of consuming all the energy of the generator a, then there will be a traveling wave a and a stationary wave. From Wikipedia, the free encyclopedia. In other projects Wikimedia Commons.

Constantinescu argued that, contrary to popular belief, liquids are compressible.

A Treatise on Transmission of Power by Vibrations. Both transmit the waves produced by oscillationsas well as the energy and power included in these waves, thus managing to transmit energy and power at small, medium, large, even very large distances, controlling and controlling the phenomena and processes from a distance or a large distance.
